Method for detecting loss of desulfurization organic components and regenerable flue gas desulfurization process

A method for detecting paths and amount of loss of desulfurization organic components in a flue gas desulfurization system, comprising:

• preparing a solution at a various process stage of the flue gas desulfurization system as a to-be-measured solution, and a pure desulfurization solution to be added to the flue gas desulfurization system for absorbing and desorbing sulfur oxides as a base standard solution, and diluting the base standard solution with water to a plurality of standard solutions containing different concentrations of desulfurization organic components;
• adjusting the to-be-measured solution and the plurality of standard solutions to have a strong acidity, respectively, such that each of desulfurization organic components in the to-be-measured solution and the plurality of standard solutions exists in ion forms;
• heating and oscillating the to-be-measured solution and the plurality of standard solutions, respectively, to substantially remove carbonate and bicarbonate ions in the to-be-measured solution;
• respectively detecting carbon elements in the plurality of standard solutions, to form a linear relationship between concentrations of the desulfurization organic components in the standard solutions and detected carbon element data;
• and
• detecting carbon elements in the to-be-measured solution, and obtaining a total concentration of the desulfurization organic components in the to-be-measured solution according to the linear relationship.
